A low fuel shut off for a portable engine-driven welder is disclosed that disables the engine when the fuel level drops below a desired level. The system includes a controller configured to receive the current fuel level signal from a fuel sensor positioned in or near the fuel tank. The controller is connected to a maintenance display that may include a fuel gauge, a visual alarm, and an audible alarm. The controller regulates the fuel supply by actuating a valve and closing the valve when the fuel level drops below the desired level. The low fuel shut off works in conjunction with a visual and/or an audible alarm alerting the operator before and/or after the engine is disabled. The controller is configured to receive data from other engine sensors and can disable the engine if the parameters reach a specified level.

An Anode Rod Depletion Indicator for use with a sacrificial anode in a fluid storage tank. A core wire, which is arranged within the anode, has a series of hollow or fluted passageways. When the anode depletion causes a predetermined amount of the core wire to be exposed, fluid contained in the storage tank flows in the hollows or flutes of the core wire. The fluid pressurizes and activates a pressure gauge or switch, or pushes a piston up to a location, which is visible to the owner. In an embodiment, a visible indicator such as “Good” is visible on a pressure gauge until the fluid pressure indicates “Replace” on the pressure gauge or until the piston pushes up a “Replace” indicator to the need to replace anode rod, to prevent corrosion and failure of the tank, while the anode is still providing corrosion protection of the tank. An electrical switch may cut off supply fluid, fuel supply, and/or activate an alarm.
